PROCESS OF MAKING JOURNAL-BOX LIIDS.

Original application filed. August 23, 1926, Serial No. 130,845. Divided and this application filed December 2, 1926.

This invention relates to journal box lids and more particularly to the process of making them from a single sheet or plate of metal.

An object of this invention is to provide a journal box lid which can. be readily made from a plate of metal with an integral pintle pin to cooperate with standard. journal box hinge lugs.

A further object of this invention is to provide a simple and eliicient process for the manufacture of such a journal box lid 3 in Which the integral pintle pin, the connecting straps and the side flanges c. n be formedbyshaping a single metal sheet or plate. 1 j

These and other objects otmy invention will be apparent from the following description and annexed drawings, in which Figure 1 is a front elevation of the blank from which one ofthe forms of my journal box lid may be -formed.

Fig. 2 is a side elevation of the blank shown in Fig. 1.

Fig. 3 is a front elevation of the lid completely formed from the blank in Fig. '1.

Fig. 4 is a side elevation of Fig. 3.

Fig. 5 is a section online 5-5 of Fig. 3.

Fig. .6 is a front elevation of a modified form of blank.

Fig. 7 is a side elevation of the blank shown in Fig. 6.

Fig. 8 is a front elevation of the lid formed from the blank shown in Fig. 6.

Figs. 9, 10 and 11 are taken on the lines 9-49, 1()-1O and'll-ll of Fig. 8.

The blank shown in Fig. 1 from which the journal box lid is to be formed comprises a body portion 1 with an aperture 2 formed 40 near its upper margin. At the sides of the aperture 2 are the members 3 whlch term the straps connecting the member 4: therewith. Wings 5 are provided which extend from the metal forming the member 41.

Projecting from the lower part of the body portion is the finger piece 6 which 1s provided for readily opening and closing the lid as is Well understood.

Serial No. 152,145.

from a single plate or sheet of metal it is then subjected to a pressing operationwhich turns down. the flanges 1" and )ifsets the finger piece 6 from the body oi? the metal plate as well as offsetting the connecting strips 3 therefrom. The metal 4 is rolled to form the pintlc as shown in Fig. 3 and the extension wings 5 at the same time are turned back and pressed against the con necting strips 3 and in the form of the invention shown in Figs. 1 to 5 are pressed to overlie and engage the face of: the body portion of the lid along its HPPUPIQJQQL' The portion 5 of the extension wings thus remforces the connecting straps and makes them considerably more rigid and may even be subsequently spot welded to the upper marginal portion of the journal box lid and to the straps, if desired.

The body portion of the journal box no. may be still'ened by suitable stiffening depressions 7 8 and 9 formed therein by press ing, asis well understood. so

In the modified form of journal box lid shown in Figs. 6 to 11, the construction is similar to that shown in Figs. 1 to 5, with the exception that the body portion. 15 or the blank is sl'lorter than the blank shown in Fig. 1 because the portion 16 of the blank which is rolled. to form the integral pintle 17 has no extensions or wings.

The blank 15 is provided with an aperture 18 near its upper margin to receive a portion of the journal box hinge lug (not shown), and the portion 16 is connected by the straps 19 to the body portion of the blank.

Surrounding the bottom, sides and a portion of the top of the blank, metal. is provided to form turned-in side flanges 15 to engage the sides, bottom and a portion of the top of the journal box to form a substantially tight joint therewith and exclude the dust and dirt from the journal box.

The body portion 15 may be reinforced f with depressions 20, similar to the depressions shown in Fig. 3 and be provided with a similariingerpiece 21.

stantially hollow,

The metal of the portion 16 is rolled to form the integral pintle 17 and the edge of the metal 16 abuts the lowerpart of the pintle, as shown in Fig. 11,. so that a subcylindrical pintle is formed without the protrusion of a free edge. i 1

lhe connecting straps 19 which connect the portion 16 with the body portion 15 of the blank may have suitable ribs or flutes No. 130,845, filed August 23, 1926, of which 1 application this'is a. division.-

Furthermore, it is to be: understood that theparticu'la-r forms of apparatus shown and; described, and theparticular procedure set forth, are presented for purposes of em planation and illustration and that various claims.

modifications of said apparatus and procedure can bemade: without departing from my invention as defined 1n the appended What I claim is 1. The method of making a journal box lid, comprising cutting from asingle metal plate a suitable metal blank provided with connecting straps and a stripof metal joining the straps, rolling the strip ofmetal to form a hollow, cylindrical pintle spaced from the body portion of the blank by said straps, and reinforcing the straps and body portion of the lid.

.2. The method of makinga journal box lid, comprising cutting from a single metal plate a suitable metal blankprovided with connecting straps and a strip of metal joining the straps, rolling the strip of metal to form a hollow, cylindrical pintle spaced from the body portion of the blank by said straps, forming integral reinforcing members in the body portion of the blank, and. reinforcing the connecting straps.

3. The method of making a journal box lid, comprising cutting from a single metal plate a'suitable metal blank provided with member or the like with an. integral hinge connecting straps and a strip of metal join ing the straps, rolling the strip of metal to form a hollow, cylindrical iintle spaced from the body portion of the blank by said straps, turning down portions of the top, sides and bottom of the blank to form integral side flanges on the lid, and suitably reinforcing the connecting straps.

4. The method of making a. journal box lid, comprising cutting from a single metal plate a suitable metal blank provided with connecting straps and a strip of metal joining the straps, rolling the strip of metal to form a hollow, cylindrical )intle spaced from the body portion of the bunk by saidstraps, forming integral reinforcing members in the body portion of the blank, reinforcing the connecting straps, and offsetting the pintle and connecting straps from the plane of the body portion of the lid.

5. The method of making a journal box lid, comprising cutting from a single metal plate-a suitable metal blank having connecting straps and a strip of metal joining the straps, rolling said strip of metal to form a hollow cylindrical pintle spaced from the body portion of the blank by said straps and offsetting the straps and pintle from the body portion of the lid.

6. The method of making a journal box 9 lid, comprising cutting from a single metal plate a suitable metal blank having a finger piece and provided with connecting straps and a strip of metal joining the straps, rolling said strip of metal to form a hollow, cylindrical pintle spaced from the body portion of the blank by said straps, and oil'- setting the finger piece, the straps and the pintle from the body portion of the lid.

7. The method of making a journal box lid, comprising cutting from a single metal plate a'suitable metal blank having a finger piece and provided with connecting stra s and a strip of metal joining the straps, rolling said stripof metal to form a hollow, cylindrical pintle spaced from the body portion of the blank by said straps, turning down portions of the sides, bottom and to of the blank to form side flanges, and oilsetting the finger piece, the straps and the pintle from the body portion of the lid.

8. The method of making a journal box lid, comprising cutting from a single metal plate a suitable metal blank having a finger piece and provided with connecting straps and a strip of metal joining the straps, rolling said strip of metal to form. a hollow, cylindrical pintle spaced from the body portion of the blank by said straps, turning down portions of the sides, bottom and top of the blank to form. side flanges, and reinforcing the connecting straps and body portion ofthe lid.

9. The method of forming a metal closure pintle which comprises cutting from a single metal plate a suitable metal blank havbody thereof and a strip of metal joining the straps and extensions projecting beyond said strip of metal, rolling said strip of metal to form a hollow cylindrical pintle 111g connecting straps projecting from the extending across the space between the straps and spaced from the body portion by said straps, and bending back said ex,- 10 tensions to overlie and reenforce said connecting straps.

In testimony whereof I aflix my signature;
